Main window does only conditionally open up when using wayland (signal-desktop 6.43.1) about signal-desktop HOT 4 OPEN

I have similar issue. Although for me I have to run signal-desktop --enable-features=UseOzonePlatform --ozone-platform=wayland in one terminal tab and then again the same in other to make signal show up. No other electron apps have those issues for me (caprine as eg.). I'm on arch KDE plasma.

Thanks for the bug report - the need for startups in both configurations is certainly unexpected.

This is likely an Electron issue - for the best chance of getting this fixed, you can help by filing a bug on their project with an Electron Fiddle showing a minimum repro.

I can confirm this as well (on signal 7.2.0 on Arch Linux with sway). I need to start signal twice for the window to open up on wayland.

The same also happens when using signal-desktop --ozone-platform-hint=auto instead of the above flags.

I debugged this using WAYLAND_DEBUG=1:

When only starting signal-desktop once:

• Signal actually creates a Wayland surface ([email protected]_surface(new id wl_surface@36))
• It also creates a fractional scale manager and viewport
• but it doesn't actually attach any buffers to the surface, doesn't commit it, and doesn't create an XDG toplevel surface (an actual window)

When starting it a second time:

• Signal commits the surface
• it also creates an XDG toplevel surface
• the window appears and basically everything works
